The varied carpet beetle (Anthrenus verbasci) is a 3 mm-long beetle belonging to the family Dermestidae, positioned in subgenus Nathrenus.They are a common species, often considered a pest of domestic houses and, particularly, natural history museums, where the larvae may damage natural fibers and can damage carpets, furniture, clothing, and insect collections.
Adult Dermestidae are generally small beetles (1–12 mm long), rounded to oval in shape, with hairy or scaly elytra that may form distinctive and colourful patterns. [3] [4] Except in genera Dermestes and Trichelodes, there is a single ocellus in the middle of the head.
The adult common carpet beetle varies from about 2.5 to 3.8 mm (0.10 to 0.15 in) in length. The antennae have eleven segments, three of which form a club, and the eyes are notched at the front. The head is black but is largely concealed under the prothorax , which is also black, liberally speckled with white scales apart from a band in the centre.
Adult carpet beetles are creepy-crawly, but ultimately harmless. However, their larvae can cause significant damage to the carpets, fabrics, and clothing they chow down on.
Anthrenus carpet beetles are small beetles a few (1.8-4mm) millimeters long with a rounded shape. Their antennae bear small clubs at the end, which are larger in the males than in females. Many have a delicate pattern, with a dark body covered in colorful scales of various brown, tan, red, whitish and grey hues.
The black carpet beetle (Attagenus unicolor) is a 3–5-millimetre-long (0.12–0.20 in) beetle that can be a serious household pest. The larvae grow to 7 mm (0.28 in) in length, are reddish brown in colour and covered with bristles.
Female carpet beetles can lay over 100 eggs which can hatch after 10–44 days at temperatures between 15 °C (59 °F) and 32.5 °C (90.5 °F), ideally at 25 °C (77 °F). [2] Four generations of carpet beetles can develop every year. It can take 9 months to 2 years for a carpet beetle to become a full adult.
The legs are covered in yellow scales. It looks similar to other carpet beetles, but its tiny body scales are rounded or oval, while those of other carpet beetles are longer and narrower. [1] Each antenna is tipped with a club. [2] During its adult lifespan of 30 to 60 days, the female beetle lays up to 100 white eggs.
